By the People (2005)

Two years after the events in 4 the People, a group of four students join up to fight corruption in education. They are angered with the suicide of a student who does not get a loan for her studies. The police department brings Rajan Mathew (Sunil) back from the administrative job that he had been shifted to for killing a student. Rajan’s investigation leads to a powerful kingmaker who controls the media and political parties. Rajan tapes the conversation. His wife is murdered, and he is crippled by the attack. He is now posted as in charge of jails. The gang that opposed corruption lead an attack on the kingmaker who lays a trap in which they get killed. Rajan employs a few members of the 4 the people, who are in jail, and uses his brains to annihilate the members of the caucus. An investigating officer (Satish Poduval) is close on the trail of the student gang and Rajan but gives up without getting any clue.
